Smugness more than likely...;) Just teasing. But people have been trying to stay out of the rain long before cars.
Unbrellas have been standard equipment in London even before Jack the ripper. Some people wearing silk stay out of the rain for a reason.
And remember the odd bit of folk wisdom dispensed by parents to disparage a suitor of their young daughters? " He doesn't have the brains to come in out of the rain."
But if you think about it a late night comedian would have a field day with a picture of a bicyclist riding to the store to get a beer in the rain. They would say the rain was the least of his problems. :lol:
